But the problem is: Mac Appstore won't even show me that there are updates available, if I'm not running the admin-account. If I didn't read Apple News sites, I wouldn't know and these updates would never be installed, because I usually don't use my admin-account.
Before Mountain Lion, Mac Appstore would show the updates and ask for my admin-password if I tried to install them.
So I guess there is something wrong with Mac Appstore on my system.

Then run the admin account now and then as a check. Or go to the Apple logo > support > downloads, which will tell you about recent available downloads. It's not the system that has it wrong unless Mountain Lion changed the support facility.

Thank you all for the hints.
I'm using Macs now for over 13 years, and I think this is very inconvinient and undermining the security of a Mac.
Why should Apple hide those updates on standard accounts? It could take days or even weeks before someone discovers there are security updates for his Mac available. This is a real step backwards in my opinion.
Hope they will fix it with Mavericks.

O.K. I finally have the solution.
Seems like the problem was the firmware of my airport base station .
I hadn't updated it for a while and two days ago the airport app started and showed me there was an update to version 7.6.4.
I installed it, and after that, my iMac began showing me updates in the Mac AppStore, although I was logged into my normal user account. Enter admin password, enter Apple ID, and presto: updates where installing, just like in the good ol' times.
What the firmware of my airport station has to do with the ability of MacOS to find updates? Don't ask me...
